A rhombus is a quadrilateral (four sided polygon) with all four sides having equal length. A square is an example of a rhombus, where all four angles are right angles. Opposite angles in a rhombus are always congruent, while adjacent angles sum to 180 degrees. When a rhombus is not a square, it is sometimes called a "diamond." A rhombus is always a parallelogram, because pairs of opposite sides in a rhombus are parallel.

In geometry, a rhombus (or rhomb) is a quadrilateral in which all of the sides are of equal length, i.e., it is an equilateral quadrangle. In colloquial usage the shape is often described as a diamond or lozenge.
In any rhombus, opposite sides will be parallel. Thus, the rhombus is a special case of the parallelogram. One suggestive analogy is that the rhombus is to the parallelogram as the square is to the rectangle. If any angle of a rhombus is a right angle, then all the angles of that rhombus are right angles, and it is then a rectangle and a square. A rhombus is also a special case of a kite, that is, a quadrilateral with two pairs of equal adjacent sides. The opposite sides of a kite are not parallel unless the kite is also a rhombus.
The rhombus has the same symmetry as the rectangle (with symmetry group D2, the Klein four-group) and is its dual: the vertices of one correspond to the sides of the other.
A rhombus in the plane has five degrees of freedom: one for the shape, one for the size, one for the orientation, and two for the position.
The diagonals of a rhombus are perpendicular to each other. Hence, by joining the midpoints of each side, a rectangle can be produced.
One of the five 2D lattice types is the rhombic lattice, also called centered rectangular lattice.
Consecutive angles of a rhombus are supplementary.

If you're referring to the shape, it's a four sided shape, that looks like a square that's been sat on, or like a square that's leaning over. All the sides are of equal length, but the angles are not right angles.

Firsly it's spelt Rhombus
but it is like a square only the two sides are bent at a 45 degree angle.

rhom•bus
Pronunciation: (rom'bus), [key]
—n.,
—pl. -bus•es, -biPronunciation: (-bī). [key]
1. an oblique-angled equilateral parallelogram; any equilateral parallelogram except a square.
2. an equilateral parallelogram, including the square as a special case.
equilateral means all sides the same length.
paralellogram means a 4-sided figure in which each pair of opposite sides are parallel to each other.

do you mean rhombus? It is a quadrilateral with both pairs of opposite sides parallel and all sides the same length, i.e., an equilateral parallelogram. The word rhomb is sometimes used instead of rhombus, and a rhombus is sometimes also called a diamond
